It's not about the combos and the various options, or the dosage, it's about the basics of taking the animal to a qualified herp vet and getting a culture done, which you would know if you had read through the links I have posted.
RI might also not be the only problems there are other things first present themselves with a RI, again you cannot know without seeing a vet, and vets do not do diagnostic online.
Coming on a forum seeking proper dosage for treatment when you don't know what you are dealing with is as useless as people using home remedy such as vicks vapor rubs for RI
Makes me wonder if your dog or cat get sick do you give them just any medicine you have on hands or do you actually get a diagnosis and give them the appropriate medicine that will specifically target the problem?
